Description

진공 단열판재, 제조장치 및 그 제조방법{Insulator Panel And Apparatus And Method For Manufacturing the Panel}TECHNICAL FIELD [0001] The present invention relates to a vacuum insulation board, a manufacturing apparatus and a manufacturing method thereof,

본 발명은 진공 단열판재에 관한 것으로서, 보다 구체적으로는 진공에 의한 단열 및 방음효과를 가지는 하니콤 형태의 단열판재 및 이를 제조하기 위한 제조장치와 방법에 관한 것이다.The present invention relates to a vacuum insulation board, and more particularly, to a heat insulation plate of a honeycomb type having a heat insulation effect and a sound insulation effect by vacuum, and an apparatus and a method for manufacturing the same.

에너지 절감을 위하여 건물 외벽의 단열은 필수적 사항으로 인식되고 있다. 건물의 냉난방에 소요되는 에너지는 건물 외벽 및 창호의 단열을 통해서 전체 에너지의 50% 이상을 절약할 수 있다는 보고가 있다. 그러므로 건물 외벽 단열재는 그만큼 중요시 여겨지고 있다. Insulation of the outer wall of the building is recognized as an essential requirement for energy saving. It has been reported that the energy required for heating and cooling the building can save more than 50% of the total energy through the insulation of the outer wall of the building and the window. Therefore, building exterior wall insulation is considered to be more important.

기존의 건물 외벽 단열재로 쓰이는 재료는 폴리우레탄 폼의 발포제인 CFC, 스티로폼, 유리섬유(glass wool) 등이 있으며, 이보다 더욱 단열성능이 뛰어난 것으로서 진공단열패널(VIP, Vacuum Insulation Panel)과 에어로겔(Aerogel)이 제시되고 있다. 유리섬유를 심재로 채운 진공단열패널의 단열성능은 유리섬유의 16배 이상, 폴리우레탄 폼이나 스티로폼 보다 단열성능이 월등히 뛰어난 것으로 평가받고 있다. 일반적인 진공단열패널의 구조는 내부의 진공도를 유지하기 위한 차폐재로서 강성이 높은 합성수지나 금속으로 된 케이싱과 그 내부에 충전되는 심재로 구성되며, 케이싱 내부는 진공이 유지되도록 하는 구조를 가진다. 심재로는 유기질 또는 무기질의 분말 또는 섬유가 이용되기도 하고 고분자 수지류가 이용되기도 하였다. 그러나 이들은 환경문제 및 장기간 사용시 단열성능이 저하되는 단점이 있다. Existing building exterior wall insulation materials include polyurethane foam foaming agents such as CFC, styrofoam, and glass wool, and are superior in thermal insulation performance. They are used for vacuum insulation panels (VIP) and aerogels ). The insulation performance of vacuum insulation panel filled with glass fiber core is evaluated to be 16 times higher than that of glass fiber and superior in heat insulation performance than polyurethane foam or styrofoam. The structure of a vacuum insulation panel in general is a shielding material for maintaining the degree of vacuum in the interior, which is made of a highly rigid casing made of a synthetic resin or metal and a core material filled in the casing, and the inside of the casing has a structure for maintaining vacuum. As the core material, organic or inorganic powders or fibers are used, and polymer resins are used. However, they have a disadvantage in that the insulation performance is deteriorated in the case of environmental problems and long-term use.

진공단열패널의 장점은 단열효과가 높고 및 내화성과 내열성이 우수하고 방음기능도 우수하다는 것이다. 그러나 가격이 비싸고 높은 강성을 유지해야 하므로 무게가 증가하도, 패널의 규격도 제한적이며, 부분적인 손상(예를 들어 진공 파괴)에 의해 단열기능이 완전히 없어지는 문제점 등이 있다. The advantage of vacuum insulation panels is that they have high insulation effect, excellent fire resistance and heat resistance, and excellent soundproofing function. However, since the price is high and the rigidity is high, the weight of the panel increases, the panel size is limited, and the heat insulating function is completely lost due to partial damage (for example, vacuum fracture).

이하, 첨부된 도면을 참조하여 본 발명의 구체적인 내용을 상세하게 설명한다. 우선 도 1 내지 도 5를 동시에 참조하여 진공단열판재의 구조를 설명한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, the structure of the vacuum insulating plate will be described with reference to Figs. 1 to 5 at the same time.

본 발명에 의한 진공단열판재는 하니콤보드(1)를 포함한다. 하니콤보드(1)는 다수의 띠가 물결모양으로 절곡된 다음 서로 지그재그 방식으로 면접합됨으로써 평면상 벌집모양으로 된 판재이다. 보통의 경우 하니콤보드(1)는 강성증대를 위하여 제작되며 여러 분야에 널리 다양한 용도로 사용되는 구조물이다. 단독으로 사용되는 경우는 많지 않으며 2장의 시트 사이에 개입되어 실내건축을 위한 격벽, 파티션 등에 널리 사용되기도 한다. The vacuum insulation board according to the present invention includes a honeycomb board (1). The honeycomb board 1 is a planar honeycomb plate formed by folding a plurality of strips in a wavy shape and then inserting them in a zigzag manner. In general, the honeycomb board (1) is made to increase rigidity and is widely used in various fields. It is not often used alone, and it is interposed between two sheets and widely used for partition walls and partitions for interior construction.

하니콤보드(1)의 구체적인 형태는 도시된 것에 한정되지 않으며 다양한 형태가 사용 가능하다. The concrete form of the honeycomb board 1 is not limited to that shown and various forms are available.

본 발명은 하니콤형태의 진공단열판재를 제조하는 장치 및 방법에 큰 특징이 있다. 이하, 그 제조방법에 대하여 먼저 설명한다. The present invention has a great feature in an apparatus and a method for manufacturing a honeycomb type vacuum insulation board. Hereinafter, the production method thereof will be described first.

제1단계는 도 2 내지 도 3에 도시된 바와 같이 적층체(1')를 형성하는 단계이다. 적층체(1')는 상면에 제2접착층(7)이 형성된 하판(11) 위에 하니콤보드(1)를 올려놓고, 그 위에 군데군데 이격부재(3)를 올려놓고, 그 위에 하면에 제1접착층(5)이 형성된 상판(9)을 올려놓음으로써 형성된다. The first step is the step of forming the laminate 1 'as shown in Figs. The honeycomb board 1 is placed on the lower plate 11 on which the second adhesive layer 7 is formed on the upper surface of the layered product 1 and a plurality of spaced apart members 3 are placed on the honeycomb board 1, 1 is formed by placing an upper plate 9 on which an adhesive layer 5 is formed.

상판(9)과 하판(11)은 같은 소재일 수도 있고 다른 소재일 수도 있다. 이들은 금속소재일 수도 있고 합성수지일 수도 있다. The upper plate 9 and the lower plate 11 may be the same material or different materials. These may be metal materials or synthetic resins.

본 발명의 실시예에 의하면 제1,2접착층(5,7)은 접착제가 함침된 시트 형태로 되어 있다. 그리고 이는 아교와 유사하게 열을 가할 때 활성화되어 접착성능을 발휘하는 특성을 가지는 것을 이용하면 좋다. According to the embodiment of the present invention, the first and second adhesive layers 5 and 7 are in the form of a sheet impregnated with an adhesive. It may be used that has properties such that it is activated when applying heat similar to glue to exhibit adhesive performance.

이격부재(3)는 하니콤보드(1)의 상면(1a) 군데군데 접착에 의해 고정될 수도 있고 단순히 올려놓음으로써 설치될 수 있다 이격부재(3)는 두께가 3 ~5mm, 한 변의 길이가 30mm 되는 합성수지 블록일 수 있다. 이격부재(3)는 후술되는 바와 같이 압착하게 되면 부서지거나 압착되도록 무른 소재가 사용될 수도 있지만, 그와 반대로 강한 소재가 사용됨으로써 압착시 하니콤보드(1)를 찌그러뜨리면서 하니콤보드(1) 내부로 인입되도록 할 수도 있다. 하니콤보드의 하면(1b)에도 군데군데 이격부재(미도시됨)가 놓일 수 있다. 이 경우 적층체의 상하부에 통기공간이 마련되므로 보다 신속하게 진공을 형성할 수도 있고 진공단열판재의 압뒤면의 구분이 없도록 하는 효과도 얻을 수 있다. The spacing member 3 may be fixed by adhesion on the upper surface 1a of the honeycomb board 1 or simply by placing it on the upper surface 1a of the honeycomb board 1. The spacing member 3 may have a thickness of 3 to 5 mm, 30 mm. The separating member 3 may be made of a material that is broken or pressed to be compressed when it is pressed, but on the contrary, when a strong material is used, the honeycomb board 1 is crushed during pressing, As shown in FIG. (Not shown) can also be placed on the lower surface 1b of the honeycomb board. In this case, since the ventilation space is provided at the upper and lower portions of the laminate, the vacuum can be formed more quickly, and the effect of preventing the separation of the back surface of the vacuum insulation plate can be obtained.

이격부재(3)의 설치 위치를 정형화시킴으로써 단열판재의 어느 지점에 이격부재(3)가 설치되어 있는지를 소비자로 하여금 인지할 수 있도록 할 수 있다. 이를 위해 상판(9)의 상면에는 이격부재가 설치되는 위치를 패턴 형태로 표시할 수도 있다(미도시됨). 이격부재(3)는 사각형으로 도시되었지만 원판 형태일 수도 있다. It is possible to allow the consumer to recognize at which point of the heat insulating plate the spacing member 3 is provided by shaping the mounting position of the spacing member 3. [ For this purpose, the upper surface of the upper plate 9 may be provided with a pattern (not shown) at the position where the spacing member is installed. The spacing member 3 is shown as a square but may also be in the form of a disc.

제2단계는 진공챔버(17) 내부에 적층체를 설치하는 단계이다(도 3 참조). 진공챔버(17) 내에서 척층체가 이루어지도록 할 수도 있지만, 적층체를 먼저 형성한 다음 진공챔버(17) 내에 투입할 수도 있다. The second step is to install a laminate inside the vacuum chamber 17 (see FIG. 3). The stacked layer may be formed in the vacuum chamber 17, but it is also possible to form the stacked body first and then to put it into the vacuum chamber 17.

제3단계는 진공챔버(17)를 밀페하여 외부공기와 차단한 다음 그 내부의 공기를 빼냄으로써 진공화하는 단계이다(도 4 참조). 본 발명의 특징에 의하면 적층체(1')가 투입되는 챔버(17)의 작업공간을 최소로 할 수 있다. 챔버(17)의 작업공간을 최소화함으로써 진공화에 소요되는 시간을 단축시킬 수 있고 결과적으로 생산성을 향상시킬 수 있게 된다. The third step is a step of vacuuming the vacuum chamber 17 by blowing the air into the vacuum chamber 17, and then removing the air inside the vacuum chamber 17 (see FIG. 4). According to the features of the present invention, the working space of the chamber 17 into which the laminate 1 'is put can be minimized. By minimizing the working space of the chamber 17, it is possible to shorten the time required for evacuation and consequently to improve the productivity.

제4단계는 상판(9)과 하판(11)을 가압하여 상판(9), 하니콤보드(1) 및 하판(11)이 접착 고정되도록 하는 단계이다(도 5 내지 도 6 참조). 이 과정에서 핫프레스(20)를 이용하여 압력과 함께 열을 함께 가할 수 있다. 접착제를 이용하여 접착하는 방법이 예시되었지만, 초음파 융착방식이나 전기용접방식이 이용될 수도 있다. In the fourth step, the upper plate 9 and the lower plate 11 are pressed so that the upper plate 9, the honeycomb board 1 and the lower plate 11 are adhered and fixed (see FIGS. 5 to 6). In this process, heat can be applied together with the pressure using the hot press (20). A method of bonding using an adhesive is exemplified, but an ultrasonic welding method or an electric welding method may be used.

이 과정을 거친 후 도 7에 도시된 것처럼 챔버를 개방하여 완성된 하니콤형태의 진공단열판재를 인출한다. 이하에서는 상기 방법을 위한 제조장치를 설명한다. After this process, the chamber is opened as shown in Fig. 7 to draw out the finished honeycomb type vacuum insulation board. Hereinafter, a manufacturing apparatus for the above method will be described.

베이스(13) 위에 설치되는 챔버(17)는 하부덮개(15) 및 실린더(21)에 의해 상하로 기동하는 상부덮개(17)로 구성되어 기밀을 유지할 수 있는 밀폐된 작업공간을 형성한다. 하부덮개(15)와 상부덮개(17)의 접함단부에는 실링부재(22,22')가 설치되어 기밀을 유지하도록 할 수 있다. The chamber 17 provided on the base 13 is constituted by a lower cover 15 and an upper lid 17 which is vertically moved up and down by a cylinder 21 to form a closed working space capable of maintaining airtightness. Sealing members 22 and 22 'may be installed at the end portions of the lower cover 15 and the upper cover 17 to maintain airtightness.

챔버(17) 내부의 공기를 빼내어 진공을 형성하기 위한 진공펌프(33)가 파이프(31)를 통해 챔버(17)의 하부덮개(15) 또는 상부덮개(19)에 연결된다. 챔버(17)를 밀폐시킨 다음 진공펌프(33)를 가동하게 되면 적층판(1')의 내부를 포함한 챔버(17) 내부가 진공화된다. A vacuum pump 33 for evacuating air in the chamber 17 and forming a vacuum is connected to the lower cover 15 or the upper cover 19 of the chamber 17 via the pipe 31. [ When the chamber 17 is closed and then the vacuum pump 33 is operated, the inside of the chamber 17 including the inside of the laminate 1 'is evacuated.

A hot press (20) is installed inside the chamber (17). The hot press 20 is a device for applying heat and pressure to the laminate 1 'placed inside the chamber 17 while vertically moving. The upper and lower actuating cylinders of the hot press 20 are installed through the center of the upper cover 19 of the chamber 17. The hot press 20 operates in a state in which the inside of the laminate 1 'is kept vacuum by the operation of the vacuum pump 33. Therefore, the finished honeycomb-shaped insulating plate material becomes a vacuum state.

핫프레스(20)의 실린더에 의해 상하 기동하는 상부덮개(19)에 매달리는 형태로 설치되는 상판(25,29)과 하부덮개(15)의 상면(15a)에 고정 설치된 하판으로 구성되며, 이들은 공히 가압판(23,25)과 히팅판(27,29)으로 구성된다. Upper plates 25 and 29 provided in a form suspended from an upper lid 19 which is moved up and down by a cylinder of the hot press 20 and a lower plate fixed to the upper surface 15a of the lower lid 15, And is composed of the pressure plates 23 and 25 and the heating plates 27 and 29.

본 발명의 진공단열판재(100)에 의하면, 많은 수의 진공셀이 구비되게 된다. 이 진공셀은 모두 독립된 상태로 진공을 유지하고 있다. 그러므로 도 8에 도시된 바와 같이 임의의 선(C)을 따라 진공단열판재(100)를 절단하더라도 진공이 손상되는 부위는 가장자리에 불과하고 나머지 부분은 여전히 진공을 유지하고 있으므로 진공단열판재로 사용할 수가 있는 것이다. According to the vacuum insulation board 100 of the present invention, a large number of vacuum cells are provided. All of these vacuum cells maintain a vacuum in an independent state. Therefore, even when the vacuum insulation board 100 is cut along the arbitrary line C as shown in FIG. 8, the portion where the vacuum is damaged is only the edge and the remaining portion is still in vacuum, so that it can be used as a vacuum insulation board It is.

위에 도시 및 설명된 구성은 본 발명의 기술적 사상에 근거한 바람직한 실시예에 지나지 아니한다. 당업자는 통상의 기술적 상식을 바탕으로 다양한 변경실시를 할 수 있을 것이지만 이는 본 발명의 보호범위에 포함될 수 있음을 주지해야 할 것이다. The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention.
